Bump schema version to 2.0.0 and refactor common definitions

- Updated default schema version from 1.0.0 to 2.0.0 in config_schema.json, events_schema.json, forms_schema.json, jobs_schema.json, migrations_schema.json, and permissions_schema.json.
- Introduced storybook-common-definitions.json to centralize common definitions for storybook context and controls.
- Refactored storybook_schema.json to reference common definitions instead of duplicating schema properties.
- Enhanced test scripts for schema validation to ensure comprehensive coverage and improved error reporting.
